I switched just before Christmas lat year and can honestly, and I mean HONESTLY say I'm annoyed at myself for not doing it sooner!
Like many, I've been using windows based machines since 3.1 and, having gone to school in England, I was 'forced' to use windows. As such, I'd become accustomed to its intricacies, and I could pretty much do whatever I wanted without having to touch the mouse..
Going to mac os was a big step for me, but I as work had just given me a new laptop I thought I'd go for it.. I'd budgeted to purchase a new laptop anyway - so I decided, after lots of research to go for it...
How frustrated I was when I first turned it on... It wouldnt do what I wanted in any way shape or form... but after a quick look on Mac 101 and Switch 101 on the apple site, I gradually managed to resolve these issues...
Now, I cant imagine doing things any other way...
I still use windows all day in work (begrudgingly-as the software I want is not available on mac os..), but its nice to come home and wake up my macbook. Event though its been sleeping all day, I know it'll start up where I left off...
As many have said, just persevere...
Best of luck with your mac experience
Tom
